This thread is supposed to become a collection of tips and tricks which can be directly app related or more generic when it comes to using the iPad in the aircraft.

External GPS support

It seems to be possible to use an external GPS with our App. At least our betatest user Alf "Major" was able to use his Garmin GLO (connected to the iPad via Bluetooth). He used it on a flight from Friedrichshafen to Berlin and observed no problems.

Overheating iPad

Viktor Strausak reported that iPads with a white frame are more stable in regards to overheating. Those with a black frame overheat more easily due to sunshine. Annette Kennedy recommends to install the iPad in a holder and position it in a way that the front of the iPad is not in direct sunlight.

Backup powersource

Many pilots voiced concern that the iPad might run out of power during a flight. A solution for this is to either use a 12V power supply (if a port is available in the aircraft) or to use an external battery pack which can charge the iPad over USB. Those are often available for a rather cheap price and can be used as backup power source in case the battery is getting too low during a flight.

Printing (as backup)

While the app has no printing option, the backup solution is to make a screenshot of the relevant area (push the power and home button at the same time) and print this screenshot via wifi printing or send it to a computer and print it from there.

Overheating iPad

Definitely use holder, I have the overheating experience on iPad 3, not on 4, do not keep it in the case in summer or on your lap or leg. Once I had to cover it with my paper map...



External Bluetooth GPS support

we noticed that several users had issues while using external Bluetooth GPS devices.

If there is no GPS position indication within the app, although the receiver is successfully paired, and an indication that a position is available on the external device, the following steps will most probably fix the issue: 

  1. Go to the “Main Settings” of the iPad.
  2. Go to “Privacy”.
  3. Tap on “Location Services”.
  4. Toggle the top row to “Off”, which will turn off “location services” for all of your apps.
  5. Reboot your iPad as follows: Press-and-hold the top button for 5 seconds, slide the red slider to power off, wait 5 seconds, then press the top button again to turn your iPad back on.
  6. Go back to Settings -> Privacy -> Location Services and turn location services back to “On” for your iPad. Also make sure that location services are specifically set to “On” for “Mobile Flitedeck VFR” as well.

After this kind of "reboot", the position provided by an external Bluetooth GPS Receiver should be indicated.

Hope that helps.

Dear all,

I used the auto-zoom feature for some time now, but I find the auto-zoom is doing more or less what it wants.

Very often the zoom level and/or centering is not very useful and needs to adjusted manually (especially in portrait orientation).

In some flights, I attempted to "not touch" the iPad at all and see how MFD VFR would adjust the zooming: the zoom came very late and I would have missed the traffic circuit every time.

I am not sure if I use the auto-zoom correctly. Maybe you want to share some hints or instruction with us.

Thank you

Frank

Dear all,

iPad overheating in summer? No problem: check the attached picture.

Bottom of the iPad is vented with outside air. No overheating, even on day with 40°C ground temperature.

No overheating for the iPad !!! - the pilot stays cool when the iPad is happy.

Have fun.

As much as I like the image... it reminds me of some laurel & hardy sketch. It's a perfect solution for a problem that should (must!) not exist in the first place.

In addition, not all aircrafts have a vent located that close... try doing this in a C172...

Hello Tobias,

I am not sure how to understand your comment. I agree that overheating of iPads is a risk scenario for ipad charting and has to be mitigated. On the other hand the iPad hardware is a consumer electronics product for the general market. Its design provisions do not include cockpit use per se, which means the operator is required to provide environmental conditions that allow safe airborne usage of an iPad. Note that not even Toughpads are designed for pilots requirements. Tablets designed for cockpit use are available from avionics systems suppliers at a much higher price.

Regarding computing power: iPad Pro has 22x computing power compared to the iPad 1st gen. GPU performance even has increased 360x. The product lifecycle of an iPad is usually 2 to 3 years maximum.

If CPU load of our app is the subject ti criticism: how much load would safely allow iPad operation in which mounting and weather conditions and on which device? Is 20% too much, and how would the charts look like in that case? It is a tradeoff between paper (no power consumption, no overheating), pre-composed charts (which is like showing a book in TV and turning pages) and a dynamically rendered depiction as in our app.

Best regards

Mark

Hi Mark,

If you have a look at the picture the original poster attached you get what I mean, I think.

I am very aware that iPad et. al. are consumer products and as such not 100% reliable. Still, if you offer a product for an app you should try to make it as compatible and as safe as possible.

20% CPU Load isn't too much. 100% isn't. But if you waste CPU-Cycles (and as a result of this) eat up 20% of battery per hour where only about 10% is necessary, that's a problem that should be addressed.

If an app leads to overheating a device (and I don't care what device it is) the reason for this should be found and eliminated. Or - if it's a device problem - the device should be excluded from use.

Don't get me wrong: I love the data you provide. But, to be brutally honest: The app in its current state is not really good.

Tobias

Hello Tobias,

thank you for your involvement and passion for our product. I can see it with the time you invest to write us. One thing I want to point out regarding your assumption, that our FD VFR would waste CPU cycles and impact safety. This is not true at all. One may miss features, but the code existing is programmed following state-of-the art Boeing and ISO software and quality management processes.

Best regards

Mark
